Basic Principles of Machine - Combustion Engine (chap. 2)

The tool that converts chemical energy from fuel into mechanical energy (energy used to propel something) through the combustion process.

Type of combustion:

• External combustion engine: the steam engine, steam turbine, closed cycle gas turbine, Stirling engine.
• Internal combustion engine : motor gasoline, diesel, gas turbine, jet engine

Classification of Internal Combustion Engine 


Usefulness:
Automotive, trucks, airplanes, power generators.
Construction:
Rotary motor (turbine, Wankel engine), reciprocating engine (back and forth).
Work Cycle:
Four steps and two steps
Ignition Method: 
Spark ignition (spark ignition engines), compression ignition (compression ignition engines)
Fuel: 
Gasoline, diesel fuel, compressed gas and, alcohol
Mixing Method: 

Carburetor and injector
Cooling Method:
Cooling water and air cooling
